Malignant neoplasm of dome of urinary bladder

This code signifies a cancerous tumor originating in the dome, or superior aspect, of the urinary bladder. It indicates a primary malignancy, meaning the cancer began in this specific bladder region rather than spreading from another site.

Use this code when documentation clearly specifies a primary malignant neoplasm located in the dome of the urinary bladder. This diagnosis is typically supported by pathology reports from biopsies or resections, imaging studies, and physician notes detailing the tumor's exact location.

• Ensure the documentation explicitly states "dome" of the bladder; avoid using for other bladder sites.
• Do not use this code for secondary or metastatic bladder cancer; those require different codes.
• Confirm laterality if specified, though the dome is a singular structure.
